[CentOS] XORG and LCD Projector
dear guys, I have a problem between my CentOS 5.5 (on Axioo notebook) and LCD Projector. When I connect my notebook to LCD Projector, it can detect my notebook. But when I press Fn + F7 to activate dual monitor between my notebook and LCD Projector it goes to blank screen. FYI, the LCD Projector is NEC but I don't know the series. I've tried to change display using dual head monitor but it has no effects. Do I need some driver?? and this is my xorg configuration : Section Device Identifier Videocard0 Driver openchrome EndSection Section Screen Identifier Screen0 Device Videocard0 DefaultDepth 24 SubSection Display Viewport 0 0 Depth 24 Modes1280x800 1024x768 800x600 640x480 EndSubSection EndSection Hope you guys can help me.

Re: [CentOS] CentOS 6 Installation on Thinkpad X220
And she changed it from AHCI to compatibility mode (had to change itto that mode to make the drive being recognized?), which is not the best setting regarding speed. Alexander: The she is actually a he :) Quite right, sorry, I'd read it backwards. So presumably either a bug in the AHCI support, or a limitation/bug of the kernel driver? jh John: Actually, this is a complete false alarm. Actual Solution: You don't have to change anything on these laptops. But it is a good tip that when installing from external cd/dvdrom, if it first does not work, change usb port and try again. I changed back the BIOS to AHCI. I was previously plugged into the top left USB port I.e. the one on the left hand side closes to the monitor or back side. When lenovo's external CDROM/DVD is plugged into this port, I am unable to install linux in general or other OS's. Once I plug it into any of the other USB ports bottom left or right, it works perfectly. No wonder I haven't found any problem posts regarding x220 and CentOS/RHEL.

Re: [CentOS] XORG and LCD Projector
A long time ago I did this. I think I was using Suse 9.3 at the time. (That's how long ago it was!!) It was so easy-- taking less than a minute-- that I don't remember how I did it. My muttbox is a Dell i600m. FnF8 is the key to switch among the video options we're talking about. This probably isn't any kind of a standard, but unless you're positive FnF7 is the right key combo, you might want to try FnF8. Make sure the projector is plugged in and then turned on before hitting the CRT combo. If an error reports the sync rate is different on the projector, change the specs running the LCD (internal) monitor. I didn't have to do this, but it might help in your situation: with things connected, turned on, and set up as above, restart hal. This will kick it to do a hardware rescan. (This has worked for me hotplugging other hardware... never tried it in a projector (2nd monitor) situation.) Hope you get this working. If/When you do, please report back how. I'm sure someone else will need to know how to do this before long. On 09/11/2011 10:52 AM Andrew 'Dewa' B.

Re: [CentOS] persistent custom lines in /etc/hosts?
I've edited /etc/hosts to add few custom IP/hostnames couples. After each reboot, I have to add them again. I've then added /etc/sysconfig/network/hosts, but it seems to ignore it or at least ignore 127.0.0.1 assignments I'm doing in it. Is there a mechanism I'm not aware of, or doing things wrong to make my custom IP/hostnames assignments permanent after network services restart? snip wwp you didnt tell us much about your centos version etc so is your networking set up statically, or is it dhcp dynamic. if the latter, then possibly that is part of the issue ive always noticed that files like /etc/resolv.conf and others can change in a generic dhcp environment ...one reason we setup almost everything statically - rh ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Much better is to be prompted for the password instead... mysql mysql -u root -p and it will prompt another option is to have ~/.my.cnf which already has your password Craig Actually, it's not in Bash history because I log in from a remote server like this: $ ssh -t dotan@1.2.3.4 mysql -u root -pSECRET That, in turn, is actually aliased to something else. Therefore the login info does appear in my _local_ alias file, but if that is compromised then there is no reason to assume that ~/.ssh/ isn't also compromised, and vice versa. Additionally, one could add a space before a command to prevent it from being written to the history, I do this when encrypting files with openssl. not exactly sure what point you are trying to make about being compromised - not all that relevant but you can still just use -p option without the password and get prompted for the password which actually solves your question. Also, since MySQL is client/server you could probably use the mysql client on your local machine and connect to the server and use encryption but that isn't what you asked. Also, presuming you are using bash on the originating machine, you would have it in bash_history, just on a different machine. The point I was trying to make is that it is generally a poor idea to put a password into a shell command whether mysql or whatever.

Bad news, IMO: I think you have a hardware problem - looks like sector 0
of your h/d has gone bad.
Got backups? Got spare drive?
Except that this hardware is on the guest and so is virtual. The image
is actually a LVM logical volume. So, it must be either a kvm/qemu or a
kernel bug. I am working on getting a bug reported, as soon as I figure
out where to report it.
Are you sure that the host o/s isn't passing a real error up? Are there
errors in the host's logfile?
mark
Turns out you were correct. I did see the same error on the host, though with
an hour earlier time stamp.
I replaced that drive and all seems well now.
Thanks for your insight.

Re: [CentOS] No MySQL password in ps aux!
Getting back to the original question, it is a feature of mysql (not of CentOS per se), but there's nothing that stops other (C) programs from doing something similar. Shortly after startup, a programmer can set things up so that command line arguments (or in this case one of them) is hidden from anyone from viewing the process table. However, even using this mechanism there is a window where, if someone looks at the process table at the right time, they will see the password in cleartext. So, despite the mysql programmers trying to minimize the chance of leaking the password it is still a risk and so the advice others have given about -p (without the password) and .my.cnf is still the best option.

Re: [CentOS] Vitualization and Partitioning
Hi, When I do the install, do I or should I setup a separate partition for guest That would be better from a performance point of view OS's? From the redhat docs, it looks like the guest OS's reside at /var/lib/libvirt/images/. This should be using files as disk files, which I did and found it to be a problem when there is heavy I/O. I may combine my windoze XP on the CentOS machine so would I need to create a partition and format that at installation? If I decide to wait and go with Windoze 7 can I still create the partition later? I would like a partition scheme that allows for easier upgrades or installs without losing data. Try using LVM then, it allows you to create and resize logical partitions, including expanding with additional hard disks in the future without having to reconfigure your VM guest (except the usual file system expansion steps) Thanks, I'm more confused now that when I started reading about this stuf.. That's my experience too, the more we read, the more alternatives/options there are, the more confusing it gets! :D ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

My understanding of aliases is I can not include additional parameters
With bash / ksh / zsh aliases you can't rearrange the parameters, but
you can always add them to the end. E.g. this:
alias .arin='whois -h whois.arin.net n +'
can be called as
.arin 64.64.64.64
and will expand the way you want. However, if you needed to have
something come after 64.64.64.64, or to be mixed in with the whois
options, you'd have to use a script or a shell function. I.e., if you
wanted to pass the name of the whois server rather than hardcode it:
.arin() { whois -h $1 n + $2; }
That can't be done with an alias (except in csh).
